Description of Related Arts

With the development of the Internet and its applications,identification technology and authentication methods have greatsignificance for the user's information security.

The traditional identification technology is based on the development oftouch technology and identifies the user's identity by a sensor sensingtouching or pressing. However, the required software and logic which arein response to and perform the process of touching and pressing arecomplex, so that the system matching user information costs a longertime, and the accuracy of the matching results is not effectivelyguaranteed. In other words, the recognition technology based on thetouch technology may has a wrong matching result, as a result, it notonly brings unnecessary trouble to the user, but also is a threat to theuser's information security.

Iris recognition technology is a bio identification technology. Iris isone of the most stable human biological characteristics and has uniquecharacteristics s, which provides basic conditions for the developmentand wide application of iris recognition technology. When using irisrecognition technology for user authentication, users do not need accessto the sensor. Compared with the traditional identification technologiesbased on the development of touch technology, iris recognitiontechnology has a greater reliability in the aspect of userauthentication results.

However, the traditional iris recognition technology also has manyproblems to limit performances. On one hand, the traditional irisrecognition technology has a low image quality to collect a user's irischaracteristics, and can only be collected at a close range. Once thedistance is relatively far, it cannot accurately capture the irischaracteristics of the user, therefore, the practical value of thetraditional iris recognition technology is not high.

On the other hand, the traditional use of iris recognition technologyuse monocular (left or right) iris characteristics s for processing, andthe positioning and environmental requirements of shooting subject eyesare very high, resulting in the traditional iris recognition technologyhaving more restrictive conditions of collecting users irischaracteristics s, and resulting in not convenience enough to shootusers. More importantly, the collected monocular iris characteristicsinformation by the traditional iris recognition technology isinsufficient, which further limits the development of the traditionaliris recognition technology.

In some embodiments of thepresent invention, the external systems comprise but not limited tosafety devices such as safety box, smart devices such as mobileelectronic devices, personal digital assistants, personal computers, andapplication programs such as online payment procedures.

The iris recognition device 100 is further communicatively connectedwith a background processing component 200, in such a manner that theiris recognition device 100 acquires the user correspondingcharacteristics and transmits the user corresponding characteristics tothe background processing component 200 to be processed such asanalysis, calculation, matching and so on. The iris recognition device100 collecting user iris characteristics can be combined with otherrecognition devices to collect biometric characteristics such as facialcharacteristics, fingerprint characteristics, voice characteristics andso on so as to follow-up identify the user's identity, thereby ensuringuser information security.

Referring to FIG. 1 and FIG. 2 of the drawings according to anembodiment of the present invention, the background processing component200 is implemented as a microprocessor, and during manufacturing of theiris recognition device 100, the background processing component 200 ismounted on the printed circuit board 30 such that the irischaracteristics collected by the iris camera module 10 is quickly andefficiently transferred to the background processing component 200 to beprocessed. In the embodiment, the iris recognition device 100 has a highdegree of integration to save assembly cost when an external system isassembled.

Referring to FIG. 3A of the drawings, another embodiment of the presentinvention is illustrated. The iris recognition device 100 is providedwith a data interface 101 in advance. The background processingcomponent 200 has a connection end 201 which is coupled with the datainterface 101 to communicatively connected the iris recognition device100 with the background processing component 200, thereby enabling datatransmission between the iris recognition device 100 and the backgroundprocessing component 200.

Referring to FIG. 3B of the drawings, another embodiment of the presentinvention is illustrated. The iris recognition device 100 and backgroundprocessing component 200 are communicatively connected by a wirelessconnection in such a manner that the iris recognition device 100 isensured to have a flexibility on specific application.

It is worth mentioning that the wireless connection between the irisrecognition device 100 and the background processing component 200comprises but not be restricted to Wi-Fi, Li-Fi, internet,communications networks and Bluetooth.

In other words, the iris recognition device 100 and the backgroundprocessing component 200 are communicatively connected by a wiredconnection or a wireless connection such that iris recognition device100 meets different using requirements.

As shown in FIG. 4A and FIG. 4B of the drawings, different amount of thefill light component 20 is provided in different embodiment of thepresent invention and the position of each of the fill light component20 can be adjusted. For example, the amount of the fill light component20 can be one and the fill light component 20 is provided on thecorresponding position of the iris camera module 10 to providesupplementary light source when the iris camera module 10 collects theusers iris characteristics, so that the quality of the user irischaracteristics images is relatively higher; the amount of the filllight component 20 can be two and the two fill light component 20 aresymmetrically provided on the corresponding position of the iris cameramodule 10 to provide supplementary light source when the iris cameramodule 10 collects the user iris characteristics. In another embodimentof the present invention, the amount of the fill light component 20 canalso be more, and each of the fill light component 20 is surroundprovided in the iris camera module 10, the present invention is notlimited in this aspect.

It is worth mentioning that the amount and position of the fill lightcomponent 20 described above is exemplary and preferable only and notintended to be limiting.

In other words, in order to improve the reliability of the iris cameramodule 10 in the user iris characteristics collection, the fill lightcomponent 20 provides supplementary light source from at least oneorientation of the iris camera module 10, so that when the iris cameramodule 10 is used to collect the user iris characteristics, the userreflective spot is reduced or the generated user reflective spot islocated outside of the iris such as the sclera region.

It is worth mentioning that when the iris camera module 10 collects theuser iris characteristics, the shooting method is infrared light blackand white photography, as the user is in general environment which hasnot enough infrared light to support this shooting process, so that highquality of user iris characteristics image is acquired by the fill lightcomponent 20 providing additional light source.

Thus, the light source provided by the fill light component 20 is LEDinfrared light source to meet the shooting needs of the iris cameramodule 10. The fill light component 20 supplements infrared lights foruser binoculus region when the iris camera module 10 collects the useriris characteristics. Wherein the iris camera module 10 is preferably aninfrared camera module, so that when the iris camera module 10 collectsthe user iris characteristics, the interference of the external visiblelight is avoided as much as possible. Furthermore, the use of the filllight component 20 will not make user binoculus region to feeldiscomfort, so that when the iris camera module 10 shoots the userbinoculus region to acquire images, a uniform brightness is formed inuser's iris region. Moreover, not only the accuracy of the user irischaracteristics acquisition is improved by the infrared light, but alsothe efficiency and reliability of the iris recognition device 100processing user authentication are enhanced.

In this preferred embodiment of the present invention, the fill lightcomponent 20 comprises a light emitting element 21, wherein the lightemitting element 21 preferably is an infrared LED light-emitting elementto ensure that under the condition of the fill light component 20providing enough additional infrared light for the user irischaracteristics collection of the iris camera module 10, the energyconsumption of the iris recognition device 100 is reduced and damagecaused to the user's eyes is avoided.

As shown in FIG. 5 of the drawings, during the user iris characteristicscollecting process by the iris recognition device 100, the iris cameramodule 10 covering the face region of the user is defined as an interiorregion, so that the when the iris camera module 10 collects the useriris characteristics, the focal point is substantially in the user'siris region and preferably the focal point is located in the pupilregion; accordingly, the fill light component 20 covering outside of theuser's face region is defined as an exterior region, so that the userface region covered by the fill light component 20 is always comprisesthe user face region covered by the iris camera module 10 and at leastone eye of the user is located in the interior region. In such a mannerthat the fill light component 20 provides additional infrared lightsource for the iris camera module 10 in any cases.

It is understandable that the light emitting element 21 of the filllight component 20 has a light emitting angle which is set to be lessthan 90 degrees, so that the supplemental infrared light source providedby the fill light component 20 is effectively utilized. It is worthmentioning that the light emitting angle of the light emitting element21 of the fill light component 20 is set to be less than 45 degree, sothat under the condition of ensuring that enough supplementary infraredlight is provided for the iris camera module 10 by the fill lightcomponent 20, the energy depletion of the iris recognition device 100 isreduced.

Those skilled in the art will understand that the light emissionintensity of the light emitting element 21 of the fill light component20 is changed with the light emitting angle. As shown in FIG. 6 of thedrawings, with the increasing of the light emitting angle of the lightemitting element 21, the light emission intensity of the light emittingelement 21 becomes smaller, and the light emission intensity of thelight emitting element 21 and the light emitting angle has a functionchange. It is understandable that, according to test results of thelight emission intensity of the light emitting element 21 and the lightemitting angle, when the light emitting angle of the light emittingelement 21 is at an angle between 0 degree and 45 degree, the luminousintensity of the light emitting element 21 changes gently; when thelight emitting angle of the light emitting element 21 is at an anglebetween 45 degree and 90 degree, the light emission intensity of thelight emitting element 21 has a rapid change.

As shown in FIG. 6 of the drawings, under an ideal condition, when thelight emitting angle of the light emitting element 21 is 0 degree, thelight emitting element 21 has the maximum light emission intensity andthe depletion energy of the light emitting element 21 is the least. In aspecific application of the invention, the iris camera module 10 and thefill light component 20 has a predetermined distance. In order to makethe fill light component 20 and the iris camera module 10 tosimultaneously act on a same object such as the user iris region, thefill light component 20 and the iris camera module 10 has an angle.According to the test result of the iris recognition device 100, whenthe light emitting angle of the light emitting element 21 is less than45 degree, the depletion energy of the light emitting element 21 is theleast, and each of the fill light component 20 and the iris cameramodule 10 has an optimal configuration state.

As shown in FIG. 7 of the drawings, a distance between the iris cameramodule 10 and the user iris is defined as z, an axle distance of theiris camera module 10 and the fill light component 20 is defined as x,an inclination angle of the fill light component 20 is defined as θ, anda formulas relationship of the z, x and θ is tan θ=z/x. Based on theformulas tan θ=z/x, a deviation value of the iris camera module 10 andthe fill light component 20 is determined. Those skilled in art willunderstand that when z is in a determinate state, x and θ have achanging rule of the tangent function. The value of x can be determinedby adjusting the value of θ or the value of θ can be determined byadjusting the value of x. In this way, the deviation value of the iriscamera module 10 and the fill light component 20 can be determined.

It is worth mentioning that, when the angle θ is reasonable, thereflective spots formed on the user iris by the light emitting element21 is reduced. Alternatively, the reflective spots is located outside ofthe user iris such as sclera region to avoid the generated reflectivespot having interference on the image quality when the iris cameramodule 10 shots the user iris characteristics. As shown in FIG. 8A, FIG.8B, FIG. 8C and FIG. 8D of the drawings, the effects of collected useriris characteristics by the iris recognition device 100 under differentstates are illustrated. Experiments show that supplement of the infraredlight as well as the light emitting angle and the light emissionintensity of the fill light component 20 enable that the reflectivespots cannot interfere the user iris characteristics collection of theiris camera module 10. Therefore, in some embodiment of the presentinvention, the angle θ is preferably less than 45 degree. In otherwords, an angle between the fill light component 20 and the iris cameramodule 10 is preferably less than 45 degree.

Those skilled in art will understand that when the light emissionintensity of the fill light component 20 cannot meet the brightness ofthe requirement of the iris camera module 10 collecting user irischaracteristics, on one hand the brightness of the light emittingelement 21 is increased and on the other hand the iris recognitiondevice 100 can be provided with two or more than two fill lightcomponent 20.

As shown in FIG. 9A and FIG. 9B of the drawings, the brightnessvariation of the user iris region under different light resources isillustrated.

As shown in FIG. 9A of the drawings, under a natural light condition,when the iris camera module 10 collects the user iris characteristics,the brightness of the user iris region is substantially gradient. Inthis case, image quality of the user iris characteristics collected bythe iris camera module 10 is poor and cannot meet user authenticationrequirements, thereby resulting in inefficient of the traditional irisrecognition technology and being difficult to guarantee accuracy.

As shown in FIG. 9B of the drawing, after the fill light component 20provides additional light resource for the user iris region, and whenthe iris camera module 10 collects the user iris characteristics, thebrightness of the user iris region is more evenly, so that it is helpfulto improve the quality of the user iris characteristics collected by theiris camera module 10 and the reliability of the iris recognition device100 during using process is improved.

It is worth mentioning that the image quality of the user irischaracteristics iris collected by the iris camera module 10 has animportant influence on the computing speed and the logic complexity ofthe iris recognition device 100, and has an impact on the recognitionrange of the iris recognition device 100. People skilled in the art willunderstand that when image quality of the user iris characteristics iriscollected by the iris camera module 10 is high, the complexity of thelogic design of the iris recognition device 100 can be reduced, so thatthe consumed time of the iris recognition device 100 on userauthentication is shortened.

In the preferred embodiment of the present invention, the irisrecognition device 100 can achieve long-distance user iris recognition,by the miniaturization of the pixel size of the image sensor of the iriscamera module 10 and the quantifiable selector mode of the crosswisepixel quantity, and combining with the design value of the lens hfov toextend the recognition distance of the iris recognition device 100, theiris recognition device 100 can be achieved the long-distance user toiris recognition by these rational design.

Specifically, the image sensor of the iris camera module 10 provides asmall diameter pixel and when the iris camera module 10 collects theuser iris characteristics, the number of pixels in the binoculus regionis at least 10 pixels/mm and the total pixel resolution of the binoculusregion is at least 1920×800 in order to meet the minimum requirements ofiris recognition algorithms. Furthermore, when the iris camera module 10collects the user iris characteristics, the resolving power of thebinoculus region is at least 450 LW/PH (0.8 F).

Accordingly, as shown in FIG. 10 of the drawings, a fill light method ofan iris recognition application of the present invention is illustrated,wherein the fill light method comprises the following steps.

(a) Provide an iris camera module 10 and the user's pupil issubstantially focal point, and collect user iris characteristics bycapturing uniform brightness from the focal point to all around.

As shown in FIG. 11A to FIG. 12 of the drawings, the iris recognitiondevice 100 is provided with a human face camera module 40, wherein thehuman face camera module 40 is mounted on the printed circuit board 30such that the iris recognition device 100 simultaneously collects theuser facial and iris characteristics, so that user authenticationaccuracy of the iris recognition device 100 is improved by increasinginformation of user characteristics captured by the iris recognitiondevice 100.

As shown in FIG. 11A of the drawings, the iris camera module 10, thehuman face camera module 40 and the fill light component 20 areintegrated on the iris recognition device 100, wherein the iris cameramodule 10 can collect one eye user iris characteristics or binoculususer iris characteristics.

The fill light component 20 is provided and disposed in the iris cameramodule 10, in particular, the fill light component 20 and the iriscamera module 10 are integrated to the binoculus iris images dataacquisition module 600 for the acquisition of the user irischaracteristics, and in the follow-up for user authentication so as toeasy to use.

It is worth mentioning that the fill light component 20 is preferably aninfrared light emitting element, so that the light generated from thefill light component 20 is LED infrared lights, in such a manner thatthe fill light component 20 supplements the infrared light for the userbinoculus region during the iris characteristics collecting process ofthe iris camera module 10, so that the user iris region has an uniformbrightness as to improve the accuracy of the user iris characteristicscollected by the binoculus iris images data acquisition module 600.Moreover, when the fill light component 20 provides additional lightsource for the iris camera module 10, the light does not causeirritation to the user's eyes. In other words, the using of thebinoculus iris images data acquisition module 600 does not affect thephysical and mental health of users.

It is also worth mentioning that the fill light component 20 ispreferably an infrared LED light emitting element to ensure that theenergy consumption of the fill light component 20 is reduced under thecondition of the fill light component 20 being able to provide enoughadditional infrared light for the binoculus iris images data acquisitionmodule 600.

In some embodiments of the present invention, the iris camera module 10is preferably an infrared camera module, so that when the iris cameramodule 10 collects the user binoculus iris characteristics, the adverseeffects of visible light to the image quality is reduced and a betterimage effect is obtained.

Specifically, the lens assembly 112 of the iris camera module 10 furthercomprises a lens 1121, a lens holder 1122, an infrared carrier penetratefilter 1123 and other components. The lens holder 1122 is mounted on theprinted circuit board assembly 113.

It is worth mentioning that the infrared carrier penetrate filter 1123filters out the visible light which through the lens 1121 and onlyallows infrared lights to cross through. In other words, the lightspassing through the lens 1121 and received by the image sensor chip 111is infrared light which carries the user iris characteristics, so thatthe interference of the visible light to the user iris image collectedby the iris camera module 10 is avoided as much as possible.

As shown in FIG. 5 of the drawings, the horizontal field angle of theiris camera module 10 is defined as the length direction of the userbinoculus and the vertical field angle of the iris camera module 10 isdefined as the width direction of the user binoculus. When choosing andproviding the angle between the fill light component 20 and the iriscamera module 10, in order to ensure that the generated light of thefill light component 20 can cover the region which the iris cameramodule 10 covers, the light emitting angle of the fill light component20 is respectively greater than the horizontal field angle and thevertical field angle of the iris camera module 10. In this way, it canmake the coverage range of the fill light component 20 to be greaterthan the coverage range of the iris camera module 10 in the sameprojection range.

In detail, during the process of collecting the user irischaracteristics of the binoculus iris images data acquisition module600, the iris camera module 10 covering the face region of the user isdefined as an interior region, so that when the iris camera module 10collects the user iris characteristics, the focal point can be locatedinside or close to the user iris region. More preferably, the focalpoint of is located in the user's pupil region.

It is worth mentioning that the area of the interior region is relativeto the horizontal and the vertical field angle of the iris camera module10.

Accordingly, the fill light component 20 covering outside of the user'sface region is defined as an exterior region. As the light emissionangle of the fill light component 20 is respectively greater than thehorizontal and the vertical field angle of the iris camera module 10, sothat the user face region covered by the fill light component 20 isalways comprises the user face region covered by the iris camera module10 and at least one eye of the user is located in the interior region.In such a manner that the fill light component 20 provides additionalinfrared light source for the iris camera module 10 in any cases.

It is understandable that the light emitting element 21 of the filllight component 20 has a light emitting angle which is set to be lessthan 90 degrees, so that the supplemental infrared light source providedby the fill light component 20 is effectively utilized. It is worthmentioning that when the light emitting angle of the fill lightcomponent 20 is set to be 0-45 degree after repeated detection, the filllight component 20 and the iris camera module 10 has a betterconfiguration effort. Moreover, under the condition of ensuring thatenough supplementary infrared light is provided for the binoculus irisimages data acquisition module 600 by the fill light component 20, theenergy depletion of the fill light component 20 is reduced.

As shown in FIG. 7 of the drawings, a distance between the iris cameramodule 10 and the user iris is defined as z, an axle distance of theiris camera module 10 and the fill light component 20 is defined as x. Apreset angle of the fill light component 20 is defined as θ. The valueof x can be determined by adjusting the value of θ. In this way, thedeviation value of the iris camera module 10 and the fill lightcomponent 20 can be determined, so that the user binoculus regioncovered by the fill light component 20 of the completed binoculus irisimages data acquisition module 600 is always comprises the userbinoculus region covered by the iris camera module 10, thereby ensuringa stability and reliability during using of the binoculus iris imagesdata acquisition module 600.

It is worth mentioning that, when the angle θ is reasonable, thereflective spots formed on the user iris is reduced or is far away fromthe user iris region when the iris camera module 10 collects the userbinoculus iris characteristics. For example, under the effect of thefill light component 20, the reflective spots is generated in the usersclera region or other positions, so that the generated reflective spothaving interference on the image quality is reduced when the iris cameramodule 10 collects the user binoculus iris characteristics.

As shown in FIG. 36 of the drawings, the reflective spot does not affectthe image quality of the user binoculus iris characteristics collectedby the iris camera module 10, so that the iris camera module 10 can bemore accurately to capture the user iris characteristics. Thus, in someembodiments of the present invention, the reasonable angle θ range is 0degree to 45 degree.

Those skilled in the art will understand that when the light emissionintensity of the fill light component 20 cannot meet the brightness ofthe requirement of the iris camera module 10 collecting user irischaracteristics, on one hand the brightness of the fill light component20 is increased and on the other hand the iris recognition device 100can be provided with two or more than two fill light component 20.

It is worth mentioning that, under the condition of providing aplurality of the fill light component 20, each of the fill lightcomponent 20 is uniformly arranged around the iris camera module 10, andwhile the angle and deviation value of each of the fill light component20 and the iris camera module 10 are adjusted, so that the binoculusiris images data acquisition module 600 has a higher accuracy on irisrecognition and user authentication.

It is also worth mentioning that the image quality of the user irischaracteristics iris collected by the iris camera module 10 has animportant influence on the computing speed and the logic complexity ofthe iris recognition device 100, and has an impact on the recognitionrange of the iris recognition device 100. Those skilled in the art willunderstand that when image quality of the user iris characteristics iriscollected by the iris camera module 10 is high, the complexity of thelogic design of the iris recognition device 100 can be reduced, so thatthe consumed time of the iris recognition device 100 on userauthentication is shortened.

Moreover, in thisembodiment of the invention, the first lens object side surface 1200 isdesigned to be unsmooth, in particular, the periphery of the first lensobject side surface 1200 forms a convex curvature which is differentwith the middle of the first lens object side surface 1200 thereof so asto modify the distorting discrepancy resulting from the increasing ofthe field angle of the camera optics lens assembly, thereby avoidingimage distortion of the user iris characteristics collected by thecamera optics lens assembly.

Furthermore, the convex design of the first lens object side surface1200 further enhances the positive refractive power of the first lens1000 in order to further reduce overall length of the camera optics lensassembly based on ensuring that the camera optics lens assembly having alarger field angle, so that the size of the camera optics lens assemblyis smaller so as to be integrated in the follow-on devices such as theelectronic devices.

The second lens 2000 is a lens having a negative focal power to providea negative refractive power, and to modify the discrepancy resultingfrom the excessive positive refractive power of the first lens 1000. Thesecond lens 2000 has a second lens imaging side surface 2100 and asecond lens object side surface 2200. The second lens imaging sidesurface 2100 towards the imaging surface 1111 and the second lens objectside surface 2200 towards the first lens imaging side surface 1100.

It is worth mentioning that in some embodiments of the presentinvention, according to the lens curvature radius, the second lensimaging side surface 2100 is a convex surface. While based on the vectorheight of the lens, the second lens imaging side surface 2100 can be aconvex or concave surface, so that the camera optics lens assembly hasdifferent operational performances.

The third lens 3000 is a lens having a negative focal power to provide anegative refractive power, wherein the third lens 3000 has a third lensimaging side surface 3100 and a third lens object side surface 3200. Thethird lens imaging side surface 3100 towards the imaging surface 1111and the third lens object side surface 3200 towards the second lensimaging side surface 2100. The third lens object side surface 3200 is aconcave surface.

It is worth mentioning that in some embodiments of the presentinvention, the third lens imaging side surface 3100 is a convex surface.

In this embodiment of the present invention, at least one side of thefirst lens imaging side surface 1100, the first lens object side surface1200, the second lens imaging side surface 2100, the second lens objectside surface 2200, the third lens imaging side surface 3100 and thethird lens object side surface 3200 is aspherical so to meet the needsof the camera optics lens assembly manufacturing the iris camera module.

It is worth mentioning that in some embodiments of the presentinvention, every sides of the first lens 1000, the second lens 2000 andthe third lens 3000 can be aspherical such that the camera optics lensassembly is configured with parameters by designing the first lens 1000,the second lens 2000 and the third lens 3000 into different shapes,thereby eliminating imaging aberration as much as possible.

Moreover, the material of the first lens 1000, the second lens 2000 andthe third lens 3000 can be selectively from plastic or glass. Forexample, when the first lens 1000, the second lens 2000 and the externalsystem 300 are made of plastic material, the camera optics lens assemblyhas a lower manufacture cost and the manufacturing difficulty is reducedto further improve the product yields; when the first lens 1000, thesecond lens 2000 and the external system 300 are made of glass material,the configuration freedom of the refractive power of the camera opticslens assembly can be increased so that when the camera optics lensassembly is manufactured into the iris camera module, the image qualityof the collected user iris characteristics is improved.

After the camera optics lens assembly is configured, the spatialposition is stable. In other words, the spatial positions of the firstlens 1000, the second lens 2000 and the third lens 3000 becomestabilized, and the first lens 1000, the second lens 2000 and the thirdlens 3000 have a certain gap in order to prevent the collision amongthemselves during the assembly of the camera optics lens assembly and soas to improve the information content of the collected user irischaracteristics by the iris camera module by enhancing the sharpness ofthe user iris characteristics image collected by the iris camera modulemanufactured from the camera optics lens assembly.
